What Is Damp Proofing in Constructions?

Damp proofing is the process of treating dampness in walls and floors by applying a water-resistant barrier or membrane that prevents moisture from coming into contact with building materials or entering a property.

Damp proofing can involve coating, injecting, or tanking walls and floors with chemical additives, waterproof membranes, or other solutions, as well as installing physical damp-proof courses (DPCs) in walls and floors to stop lateral movement of water.

Applying damp proofing solutions can help extend the life of your property’s building materials and prevent damage from occurring due to damp.

Is Tanking The Same As Damp Proofing?

No, tanking and damp proofing are not the same. Tanking is a term used to describe the process of waterproofing an area, typically under or around a building such as a basement or an outdoor area exposed to water ingress.

This process typically involves coating or covering the walls with an impermeable material, such as concrete or a waterproof membrane, which will stop any water from entering and causing damage.

Damp proofing on the other hand refers to using a damp proof course between two layers of brickwork to protect it from rising damp, which can cause mould and other problems if not treated properly.

What Is The Best Damp Proofing System?

Kiesol C is the most powerful damp proofing cream available. With a silane content of 80%, it has the highest concentration available and offers a permanent horizontal barrier against rising damp.

Its installation is effortless, utilizing low pressure injection to guarantee an exact amount.

What Is The Difference Between Damp Proofing And Waterproofing?

Damp proofing and waterproofing are both methods used to protect foundations from moisture, however there is a distinct difference between the two.

Damp proofing is typically concerned with keeping out ground water, while waterproofing seals off the property from all sources of moisture including outside air.

Damp proofing works by interrupting capillary action and stopping moisture from travelling up through walls of a building or into walls of an underground structure, while waterproofing creates a physical barrier that prevents the movement of any kind of liquid (water or otherwise).

Therefore, damp proofing is generally seen as more effective in protecting foundations against surface water seepage and penetrating damp caused by hydrostatic pressure, while waterproofing helps protect against flooding and damage caused by drains or sewage systems.

What Are The Damp Proofing Methods?

Welcome to our blog post discussing the different methods of damp proofing. There are a variety of solutions available to ensure that your property is protected from the damaging effects of moisture, and we’ll explore each in detail.

We will discuss membrane damp-proofing, guniting, surface treatment, integral damp-proofing, cavity wall construction, pressure grouting and cementation techniques.

With the right knowledge and techniques, you can make an informed decision on which solution is best suited to your home or business property. Let’s dive in!

Membrane Damp-Proofing

Membrane damp-proofing is a popular method used to protect structures from the effects of moisture.

It works by creating an impermeable barrier that prevents moisture from passing through the structure, keeping it dry and preventing damage from occurring.

The membrane can be applied in several different ways, such as painting it onto masonry walls or injecting it between layers of concrete blocks.

Regardless of the method chosen, a membrane damp-proofing solution provides long-term protection against water and moisture which cannot be obtained through other methods.


Guniting is a popular method of damp proofing that involves spraying dry cement, sand, and water onto the walls of a building.

This creates an impermeable layer which is extremely effective at preventing water from seeping through walls and into the interior of the building.

The process usually requires professionals with specialized equipment to complete properly, and can be used on both solid masonry walls as well as hollow cavity walls.

Guniting often provides successful results when used to repair cracks or other defects in existing construction, making it an excellent option for damp-proofing your home.

Surface Treatment

Surface treatment is one of the common methods of damp proofing and is usually used to treat existing walls or foundations that are already in place.

Surface treatments involve applying a water-resistant material, such as a specialized sealant or membrane, to the surface of the wall or foundation.

This type of damp proofing can be used both externally and internally and will help keep out moisture from entering the walls or structure. It also helps prevent further damage from occurring due to water seepage.

Integral Damp-Proofing

Integral damp-proofing is a method of preventing moisture from rising up through the masonry elements of a property, such as brick walls.

This type of damp proofing involves installing a layer of material that acts as a barrier between the property and the ground surrounding it.

Usually this consists of either plastic or bituminous sheets that are placed beneath and against the foundations, to prevent water vapour from travelling up in to the home.

Integral damp-proofing is an effective way to prevent problems caused by rising damp, including mould, decay and timber rot.

It can also help to improve energy efficiency in homes by reducing unwanted air infiltration from outside sources.

How Do You Know If Your House Needs Damp Proofing?

Damp proofing your home is an important part of upkeep and maintenance, and one of the first signs that it may be required is the presence of damp patches on walls or ceilings.

Other indicators can include peeling wallpaper, musty smells, bubbling paintwork, crumbling mortar between bricks and visible mould growth.

You should also pay attention to any changes in temperature in different areas of your house – if certain rooms feel noticeably colder than others this could be a sign that rising damp has occurred due to penetrating rainwater.


If you suspect any issues with dampness, it’s best to take action quickly before any further damage is caused.
